SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 286,768, dated October16, 1883. Application filed my 23,1833. (Model.)

To all whom t may concern:

Be it known that I, DANIEL A. BOLT, a citizen' of the United States,residing at Harrisburg, in the county of Dauphin and State ofPennsylvania, have invented new and useful Improvements in Seal-Locksfor Freight and i Stock Cars, and I declare that the following is suchclear, full, and exact description of the invention as will, with aid ofthe accompanying drawings, making a part of this speciication, enableothers skilled in the art to which it appertains to make and use thesame.

My invention ybelongs to that class of devices `known as seal-locks,77in which the adjustprovided with attaching-plate, whereby it is appliedto the door-stop in such manner as to project horizontally through thesame toward the door, providing the easing also with an extension at itsouter end for the insertion of a sliding` key in it, whereby the lockingand sealing is effected in a peculiar manner; second, a swiveled boltheld in said casing by a collar on its inner end next the door, and bythe operating-handle on its outer end, said handle having a stopthereon, which, setting in a seat in the end of the casing, limits thethrow or rotary movement of the bolt to bring alongitudinal slot thereinin right position for the sliding key to drop ,vertically through it bygravity, at the same time that the projecting button or dart-head on theinner end of the bolt is turned at right angles to a vertical slot intheface-plate or keeper on the'door, through which said button engagesto hold the door shut; third, a seal-key adapted to. be permanentlyattached in the casing and stop the rotary bolt in locked position, andhaving on its upper end a seal-link, which, with the transverse slot inthe foot of said key, aifords a means for inserting any approved sealappitnce, by which the said key will be kept inserted in position whenthe bolt is locked, as will be hereinafter more clearly shown.

In the accompanying drawings, Figure l is y a side elevation, showingthe lock-bolt, sealkey, and seal-link in position as when the cardoor islocked and ready to receive the seal, which will pass through the lowerends of the seal-key and seal -link and connect them. Fig. 2 is a planof the keeper or escuteheon, viewed from the side toward the car-door,when in position on it, showing the button of the lock-boltinserted-through it, and turned a `'quarter-turn, as in position whilelocking. Fig. 3 is an elevation of the outer end of my device, showingthe lock-bolt, seal-key, and seal-link in locked position, with a loopedwire and seal applied, connecting said key and link below. Figs. 4, 5,and6 represent, respectively, the seal-key, the lock-bolt, and thecasing or shell of my lock, the easing being in longitudinal section.Fig. 7 representsafront elevation of my lock mounted on the doorstop ofa car, and locking the door thereof, both by padlock and by sealattachment, as a secure seal-lock.

,Similar letters denote similar parts in all from said door.

The letters C D E denote the lock-bolt. C is its cylindrical body, withslot Z corresponding with the seat F in the easing, and with the blade Hof the seal-key H L.

C denotes an angular tenen, to which is fastened the handle B, by whichthe bolt is rotated to a limited extent, a stop, Q, on the handlestopping it in the end of a eut-away, K,

in the casing when the slot Z and the seat F are in line, to facilitatethe insertion of said blade H of said key. Said key drops to place bygravity the instant handle B is fully lifted.

Vhen said key is fully lifted in said seat as far as the rivet V throughthe slot N in the key permits, the said handle B drops by gravity,thereby turning said bolt to right, so that the button or dart-head Emay freely enter IOO casing thereat.

the slot XV of the escutchcon or face-plate T on the edge of the door.-\Vhen said handle is elevated, as shown in Figs. 1 and 3, Jthe button Eis reversed to be in locking position, as shown in Fig. 2. The neck R onthe bolt neatly iills said slot IV transversely, to prevent rattling bythe door. The said button is oval or peaked, that it may readily iindits Way into said plate Without liability to bang by missing the slotWV, which is made long to compensate for sagging of the Wood-Work.

Letter D denotes a collar on the lock-bolt, which, With the part Bf,keeps the bolt swiveled in the barrel A ofthe casing, thus constitutinga strong lock, and one not likely to be broken;

The seal-key H L is surmounted with the head H, through which isattached the link G. Adjacent to said head Hthe keyis shouldered to shedrain and snow from the slot F, that the parts may not became stuck byice and rust.

On the front side of the extension M of the casing is the lug XV, havingeye X therein, in which the shackle of a padlock may be inserted,thereby locking the link G in place, and thereby keeping the seal-key H/inserted in locking position when the bolt C D E is locked. The padlockcan be used or omitted at option.

Moreover, the device is made a seal -lock as follows: A looped Wire, S,is shown in the link G, and in the seal slot or eye L, having its endsembraced by a seal, S. Any other approved device may be used forcoupling said link and key, and thus retaining said key in lockedposition in said sea-t F, and inserted in the bolt C D E.

For illustration, said device may be modified as follows: Instead of theeye L being in the lower end of the key H L, said key may be madeshorter, and not protrude through the casing, and a corresponding eyemay be formed in a lug closing the aperture in the best appliedinverted. The seal Wire or con- The lock 'is then, however,

scenes nector is inserted through said eye and through said link andcouples them, as before recited.

It is evident either the seal or padlock can be used or omitted, orboth, if desired, as my lock is a good door-fastener Without eitherpadlock or seal, but a better one with them applied.

WV hat I claim is- 1. In a car-door lock, the combination ofthe casing AM, having vertical receptacle F intersecting the bore P therein, andflange A,

for attaching the same, with the locking-bolt to the latter and coupledoppositely by seal Wire or band, S, inserted through it and eye L, forholding said key in slot Z in said bolt to prevent its movement,substantially as set forth.

3. In a seal-lock for engaging the plate T on the edge of a door, thestaple WV on casing A M, arranged to projectthrough` the link G andadmit the shackle of a padlock through it exterior to said link, incombination with lock-bolt C D IE and the key H, for preventing saidbolts rotary movement, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my invention I have hereuntoset my hand this 21st day of May, A. D. 1883.
